3. Prepare the Gate
• The gate must be plumb, level, and swing freely on its hinges.
• The gate must move throughout its arc without binding or dragging on the ground.
• Wheels must NOT be attached to the gate.
• Gates over 250 lb. should have ball bearing hinges with grease ttings.
• Post must be secured in the ground with concrete (minimizes twist/ex when the operator is
activated).
• Make sure there is a stable area for mounting the gate bracket (this may require the addition of a
horizontal or vertical cross member).
• We recommend you position the operator near the center-line of the gate to keep the gate from
twisting and exing, and to avoid back-splash from rain.
